CHAPTER 3 THE UNDERTAKING

3.1 Name of the Undertaking Town of Gander Wastewater Treatment Plant

3.2 Purpose/Rationale/Need for the Undertaking The proposed project is a new Wastewater Treatment Plant (WWTP) located in Gander, NL. The purpose of the Project is to replace existing wastewater treatment facilities that do not meet the current Federal Wastewater Systems Effluent Regulations (WSER). The new WWTP will be designed to meet future wastewater treatment demands for the Town of Gander (herein referred to as the ‘Town’). The Town is currently serviced by two (2) WWTPs. The Beaverwood WWTP, a hydrodynamic separation plant, services the Southeast part of the Town. The Magee Road WWTP, an extended aeration plant, services the Northeast portion of the Town. The Beaverwood WWTP discharges to a stream that is tributary to Gander Lake, while the Magee Road WWTP discharges to Whitman’s Pond and, ultimately, to the Gander River. Current effluent sampling results indicate that neither treatment system meets WSER requirements. The Beaverwood WWTP sewershed contains areas serviced with combined sewers. This plant was designed to accommodate large volumes of flow, but is still reported to overflow during extreme rainfall events. The overflow is located upstream of the headworks; therefore, wastewater that discharges via the overflow is not treated. The Magee Road WWTP is located in an area of Town experiencing significant growth. This facility is currently operating at approximately 95% capacity and cannot accommodate future growth. Land in this area is becoming increasing valuable for development. Further, the Town has received odour complaints from nearby residents. The design population has been projected to be 17,500 in 2040. This reflects the fact that the Town is growing rapidly, and that continued rapid growth is expected, although at a somewhat lower rate (8% per 5 years) than the last few years (11% per 5 years). Future growth is assumed to expand the current built-up area at a similar density to the current Magee Road WWTP catchment. The 2015 population is approximately 12,000, as projected from 2011 census data, and 5,500 more people are projected to join the Town in the next 25 years (Statistics Canada 2017).


The new WWTP will include preliminary, primary, and secondary levels of treatment as well as effluent disinfection to mitigate the effect of the effluent discharge on the receiving water. The facility design will consider residuals handling procedures in order to safely and effectively handle wastewater treatment residuals such as screenings, grit, and sludge. Further details of the project are described in section 4.2.1. The project delivery method for the new WWTP is the Design-Build method. By this method, a short-listed group of contractor-engineer teams will respond to a Request for Proposals which outlines the performance requirements for the WWTP. The successful proponent becomes the Design-Build contractor.


CHAPTER 4 DESCRIPTION OF THE UNDERTAKING

4.1 Geographic Location The proposed location of the wastewater treatment system is approximately 3 km East of Cooper Boulevard in Gander, NL (Figure 4.1 and Figure 4.2 in Appendix A). Located South of Whitman’s Pond, treated effluent would be discharged to Whitman’s Pond, which flows to Jonathan’s Pond, which is outside of the Gander Lake watershed. There are no marked water bodies identified on the proposed site. The project site will be accessed via newly constructed roads constructed from Cooper Boulevard. The proposed project would be located on Crown Lands and land controlled by the Gander International Airport Authority (GIAA); the property area, including the site, access road and sewer easements, is approximately 44 hectares. The proposed lot property boundaries for the WWTP are:

Northwest boundary – N 5428347.04, E 408669.50

Northeast boundary – N 5428510.67, E 409039.34

Southwest boundary – N 54 27809.24, E 408907.44

Southeast boundary – N 5427972.87, E 409277.28. The Town is in discussions with the Crown and the GIAA for the procurement/lease of these properties. The site is situated in a rural area removed from future development. This proposed WWTP location is currently forested, and as such some areas of the site will be cleared and grubbed during site preparation. This location was selected as the preferred option of several sites under consideration, as adequate separation distances from the Town are easily achieved at this location. Accordingly, the risk of exposure to odours is minimized.

4.2 Physical Features of the Undertaking 4.2.1 Description of the Project The Town intends to design and construct the WWTP to treat wastewater at variable rates. A 60-year life span for structural components and a 15-25 year life span for mechanical, electrical and instrumentation components are anticipated. Project components will include the WWTP proper,

new access roadways, new trunk sewers and an outfall. Major features are described below.


4.2.1.1 WASTEWATER TREATMENT FACILITY The new WWTP will include a number of major features, which are described, in general terms, below. The exact number of these features, materials of construction, and configuration will be determined by the Design-Build contractor.

Process building(s): These will contain preliminary treatment equipment, offices, control room, electrical room, and process equipment that must be sheltered, such as blowers and UV disinfection units. It is anticipated that 1-3 process buildings will be required.

Large basins for solids removal: These basins are unaerated to promote effective settling of solids from the wastewater. These may be constructed of earthen berms lined with an impervious liner, or of concrete or fibreglass-reinforced plastic.

Large basins for biological organics removal: These basins are typically aerated actively or passively to foster the growth of microorganisms to metabolize and remove the organic matter in the wastewater. These may be constructed of earthen berms lined with an impervious liner, or of concrete or fibreglass-reinforced plastic.

The design of the WWTP processes and equipment, including the major features, will comply with the more stringent requirements from the following list of design guidelines, which cover all aspects of the design of wastewater treatment facilities:

Atlantic Canada Wastewater Guidelines Manual for Collection, Treatment, and Disposal (Environment Canada, 2006).

Guidelines for the Design, Construction and Operation of Water and Sewerage Systems (NL Department of Environment and Conservation, Water Resources Management Division, 2005).

Recommended Standards for Wastewater Facilities, “Ten State Standards” (Great Lakes – Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers, 2014).

The WWTP will include the following levels of treatment, as a minimum, as shown in Figure 4.3:

Figure 4.3: Proposed WWTP treatment unit operations The exact equipment and configuration will be determined by the Design-Build contractor, but a typical process train is described below:

Preliminary Treatment uses automated screens and/or grit removal equipment to remove large, non-biodegradable solids. This produces a “screenings” waste stream and possibly a “grit” waste stream, both of which must be removed from site and disposed of in an approved waste-disposal facility such as a landfill. The total annual volume of screenings projected to be produced under 2040 design flow conditions is 73 m³.

Primary Treatment uses large, quiescent tanks to provide conditions for settling out of fine solids. This produces a “sludge” waste stream which is typically dewatered, and may be partly biodegraded on site to stabilize it before eventual removal from site and disposal in an approved waste-disposal facility such as a landfill.

Preliminary Treatment: Large solids

removal

Primary Treatment: Fine solids removal

Secondary Treatment:

Organic matter removal

Disinfection: Pathogen

deactivation


Secondary Treatment uses large, usually aerated tanks to provide conditions for microbes to metabolize and remove organic matter. This produces a “sludge” waste stream which is typically dewatered, and may be partly biodegraded on site to stabilize it before eventual removal from site and disposal in an approved waste-disposal facility such as a landfill. The total annual volume of sludge (primary and secondary combined) projected to be produced under 2040 design flow conditions is 3,000 m³/year, assuming 15% solids.

Disinfection uses banks of ultraviolet (UV) lights to deactivate pathogens so that they cannot reproduce. This produces no waste streams. Chlorination and dechlorination will not be used for disinfection because of the risk of unacceptable chlorine release into the receiving water.

The WWTP will produce effluent of a quality that meets or exceeds the values presented below in Table 4.1, in accordance with WSER and Provincial requirements.

The site will be equipped with security perimeter fencing system around the perimeter of WWTP and a gated entry at the access road to the WWTP. The fencing and gate shall deter and delay unauthorized entry or access by animals or humans, control the exit and entry through designated openings. A security system will be developed to monitor boundaries of the facilities and detect attempts at unauthorized entry and exit. The site layout will be designed so that surface water does not drain into treatment process units. All surface storm water will be piped underground to a natural drainage course. Adequate drainage slopes and pipes shall be provided to accommodate run off along any earthworks or structures constructed. Drainage from access roads and parking lots shall be captured and discharged to a common location, as approved by the Town and authorities having jurisdiction.

The WWTP will rely on electricity to operate most of the equipment required for operations. An emergency generator will be located on site to provide power to all the equipment in the case of a power outage so that releases of inadequately treated effluent and excessive odours do not occur due to loss of power. 4.2.1.2 LINEAR INFRASTRUCTURE Sewers and force mains will connect the existing Town sewers at the locations of the current WWTPs to the proposed WWTP. The proposed linear infrastructure will include approximately 4.3


km of new sewers and sewage force mains, and one sewage lift station (Figure 4.2). Much of the proposed locations are currently forested, and will need to be cleared in order to construct the pipelines. Sewer pipes and water mains shall be installed in separate trenches with a minimum of 3 m of undisturbed soil in between. Sewer pipes shall have a minimum cover of 1.8 m to prevent freezing. 4.2.1.3 ACCESS ROAD The access road will be 2.2 km long and will connect Cooper Boulevard in Gander to the proposed WWTP site (Figure 4.2). A new entrance will be established off of this new roadway to give direct access to the site. The roadway will run adjacent to the proposed new trunk sewer alignment to the WWTP, and power will be brought to site along the access road. The road will have a minimum width of 6 m. The proposed cleared road alignment is 15 m in width. The new access road and onsite parking lots shall be serviceable and free draining under all weather conditions. 4.2.1.4 OUTFALL DITCH AND EFFLUENT DISCHARGE The outfall ditch will connect the WWTP to in Whitman’s Pond (Figure 4.2). The WWTP shall produce water of quality that meets or exceeds the values presented below in Table 4.2. Table 4.2 Treated Effluent Quality Objective

4.2.2 Physical and Biological Setting Setting & Major Vegetation: The project is located in the Northcentral Subregion of the Central Newfoundland Forest Ecoregion. The Ecoregion is characterized by the Hylocomium-Balsam Fir (Hylocomium splendens and Abies balsamea respectively) forest type. As result of fire occurrences, much of the Hylocomium-Balsam Fir forest type has been converted to a black spruce (Picea mariana) forest type with white birch (Betula papyrifera) and aspen (Populus tremuloides and P. grandidentata) hardwood forests noted at richer sites. Aspen within the Central Newfoundland forest is more abundant than in other regions. Other species that are abundant in other regions, but absent within the Central Newfoundland Forest, include yellow birch (Betula alleghaniensis) due to the short frost-free period. Unique to this subregion, the high summer temperatures may stimulate aspen root suckering and contribute to the local success of aspen (Damman 1983). This subregion can be susceptible to regeneration failure due to low moisture, coarse soils and the prevalence of black spruce cover types. Succession to dwarf shrub heath dominated by sheep laurel

(Kalmia angustifolia) may occur where tree regeneration is lacking, and nutrient-poor, coarse textured till is present. The Project site itself is relatively flat, heavily forested, and falling slightly in elevation from west to east. The Ecoregion is generally characterized with rolling to undulating topography below 200 m. Forestry: The Project is located in Forest Management District 5 of the Eastern Region of Newfoundland. There are no known Corner Brook Pulp and Paper Limited (CBPPL) Timber Harvest Rights on the property. Soils: Soils within the region are generally medium quality till that is shallow, lighter in colour, and has lower organic matter content compared to other ecoregions. The soil texture ranges from sandy loam to loam. Soils in the northern part of this ecoregion can display moisture deficiency, because of seasonal warm summer temperatures and high evapo-transpiration losses (Government of Newfoundland and Labrador 2017). Shallow groundwater is present in the project area ranging from 0.2 to 3.7 m (Englobe 2016; Appendix B). Climate: The Central Newfoundland Ecoregion has the highest summer and lowest winter temperatures of the Newfoundland ecoregions (Government of Newfoundland and Labrador 2017). The coldest day on average is recorded in January and February (daily average -7.1 °C), with peak summer temperature observed in July (16.3 °C, Environmental Canada 2017). Despite an average summer temperature above 0°C, night frost can occur in any summer month (Government of Newfoundland and Labrador 2017). Average annual precipitation is 1,270.2 mm, with most precipitation falling as rain. The highest precipitation is recorded in December with an average of 126.7 mm (Environment Canada 2017). The Northcentral sub region is known to higher summer maximum temperatures, lower rainfall and higher frequency of fires than the other regions of Newfoundland (Government of Newfoundland and Labrador 2017). Prevailing winds at this location are to the west, and will generally be in the direction of populated areas (Environment Canada 2017). Hydrology: Whitman’s Pond is located approximately 200 m north of the proposed WWTP. Whitman’s Pond is within the Jonathan’s Brook watershed and flows to Jonathan’s Pond, which is outside of the Gander Lake watershed. The Jonathan’s Pond series of lakes is used for recreational activities (camping, swimming, canoeing, etc.). Surface water generally flows northward from the site toward Whitman’s Pond or east toward a wetland located south of Whitman’s Pond. Whitman’s Pond is a shallow lake, with an average depth of 1.2 m and a maximum depth of 2.2 m (D Keefe, pers. comm. March 21, 2017). Whitman’s Pond currently receives effluent from the Magee Road WWTP. Sampling by NL ECC Aquatic Research Program found that the background conditions of the Pond exceeded the CCME guideline for iron (2004 and 2005), and Chlorophyll A (2004). The othro-phosphate concentration range from 30 to 40 µg/L in 2004 and 2005. Wildlife and Species of Concern: Common mammal wildlife that may be present within the Project area include moose, snowshoe hare, Arctic hare, fox, muskrat, otter, mink, black bear, beaver, lynx, and other small fur bearing mammals (Government of Newfoundland and Labrador 2016). Bird species that may be present in the forest vegetated areas include raptors species (Bald Eagle, Osprey, Merlin, Boreal Owl, Great Horned Owl and Sharp-shinned Hawk), and grouse species (Ruffed Grouse and Spruce Grouse). The Project is located in close proximity to the Whitman’s Pond area


identified in the Gander – Benton Stewardship Agreement, which provides productive waterfowl wetlands, with abundant aquatic vegetation providing important cover for protection from predators (Government of Newfoundland and Labrador 2007). Waterfowl species that may be observed include Green-winged Teal, Ring-necked Duck and Canada Goose. Within the Gander region, the Gander River is located approximately 12 km north of the Project and is designated as Scheduled Salmon Rivers (DFO 2017a, b). Species present within Whitman’s Pond include brook trout, Atlantic salmon, three spined stickleback, and nine spined stickleback (D Keefe, pers. comm. March 21, 2017). Both Atlantic salmon and brook trout have special harvesting management plans for this area (DFO 2017b). Also within the watershed (Jonathans Pond), American eel can be present (D Keefe, pers comm. March 21, 2017). The Atlantic Canada Conservation Data Centre (AC CDC) documented 2 rare plant observations and 80 rare animal observations within 5km of the Project. Of the 80 rare animal records, the following species of conservation concern were observed: Rusty Blackbird, Gray-Cheeked Thrush, Barn Swallow, Olive-sided Flycatcher and Red Crossbill. The remaining species observed where not provincially or nationally listed, but are considered rare on the island and include American Tree Sparrow, Brown Creeper, Bufflehead, Mourning Dove, Northern Goshawk, Northern Harrier and insects. The 2 rare plant records included species that are not provincially or federally listed, and outside of Newfoundland & Labrador are not considered globally rare (A. Durocher, AC CDC, pers comm. March 21, 2017). Based on AC CDC Expert opinion maps of provincially and federally listed species, no species have been identified within 5 km of the project location; however, the Expert Opinion Maps suggest that banded killifish presence is possible, while boreal felt lichen, Newfoundland marten and Short-eared Owl are possible, but unlikely (A. Durocher, AC CDC, pers comm. March 21, 2017). Species of conservation concern are species that are protected by provincial and/or federal legislation. Species that are or may be found in the project area include the following (Table 4.3): Table 4.3 Species of Conservation Concern

Protected Areas: There are no existing Provincial protected areas or Federal parks/reserves on the property; however, the Project is located upstream of the Jonathan's Pond Provincial Park reserve. The Town of Gander signed a Municipal Wetland Stewardship Agreement with the Province of Newfoundland in 1993 and recommitted to this initiative in 2007 for another 30-year period. Several wetlands and waterbodies were identified as part of this agreement, including the area around Whitman’s Pond and a 100 m area from the high water mark, and associated marsh south of Whitman’s Pond (Government of Newfoundland and Labrador, 2007). The construction and operation of this proposed WWTP will align with the initiative as stated in the Stewardship Agreement.

4.3 Construction Regular Project hours for construction are to be Monday to Friday from 07:00 to 18:00 hours and on Saturdays, Sundays and statutory holidays from 08:00 to 17:00. Approval is required to work


outside of regular hours or days of the Project. Request approval from the Owner’s Engineer at least 72 hours in advance if work is scheduled outside these times. The site will be prepped, backfilled, graded, and compacted for the purposes of construction. All surfaces within the boundary of the WWTP will be either newly paved, top soil and seeded, sodded, planted, undisturbed or low maintenance river stone around tankage. Buildings, hardscape, roads and parking areas will not be developed within 30.5 m of any natural wetlands or watercourses. Excluding buried infrastructure, power sourcing and road access, no component of the treatment facility shall be constructed within a 25 m buffer around the entire site perimeter. The following construction activities will be required for site preparation activities:

Site clearing (road and site);

Site excavation and backfilling;

Site compaction;

Roadway construction;

Construction of onsite infrastructure;

Paving;

Use of temporary facilities;

Security perimeter fencing installation;

Storm water management; and

Sodding and seeding.

4.3.1 Environmental Impacts during Construction The Project will be designed and constructed so as to minimize risk and potential environmental impacts. Potential environmental impacts that have been identified include:

Removal of vegetation;

Disruption of wildlife, including fish;

Silt and sedimentation runoff;

In-water works (outfall placement);

Smoke from brush burning;

Dust;

Construction debris;

Risk of fuel, lubricant and hydraulic fluid release;

Airborne emissions from construction equipment;

Noise pollution from construction activities; and

Temporary disruption of traffic.

4.3.2 Potential Source of Pollutants during Construction Potential sources of pollutants that may occur as a result of construction include the following:

Spills and releases (sewage from temporary toilets, fuel, lubricant and hydraulic fluid

release);

Silt and sedimentation runoff;

Airborne exhaust emissions from construction equipment;

Noise from construction activities;

Dust; and

Construction debris.


4.3.3 Mitigation Measures The Town and their contractors will follow all specified permit conditions and construction best management practices during construction. The following project specific mitigation measures will be implemented during construction so as to mitigate potential sources of pollutants from entering the environment:

A site specific Environmental Management Plan (EMP) will be developed and followed.

All debris and waste materials will be disposed of in accordance with the latest regulations respecting Solid Waste Resource Management issued by the Newfoundland and Labrador

Department of Municipal Affairs and Environment (MAE). Non-hazardous construction and demolition debris will be either recycled or salvaged; items may include cardboard, metal, brick, mineral fibre panel, concrete, plastic, clean wood, glass, gypsum wallboard, carpet and insulation. A construction waste management plan will be developed and will include designated specific area(s) on the construction site for segregated or comingled collection of recyclable materials.

On completion of the Project, all construction equipment, surplus materials and temporary works will be cleared away and removed from the site.

Temporary weather tight enclosures and protection for exterior openings will be used until permanently enclosed.

Only new or reused, clean materials will be used for the purposes of backfill, and grading.

Surface soil stripping will be minimized where possible; material will be stockpiled and reused where possible.

Dust mitigation measures will be implemented. Specific measures might include dust suppression activities such as wetting of the construction areas and sweeping and washing of paved road surfaces.

All equipment used on site will be in good working order to reduce effects of noise.

All construction activities will occur during working hours as defined in the permit.

As required, traffic control will be provided by certified traffic control persons, in accordance with the Traffic Control Manual issued by the Newfoundland and Labrador Department of Transportation and Works. Access will be maintained for all emergency vehicles in construction areas.

The Project will be designed to minimize disruption to existing natural areas. All removal and disposal of trees, brush, stumps, surface litter, boulders and grubbings will follow applicable permits and best management practices.

An Erosion and Sediment Control Plan will be implemented prior to construction and will describe the measures implemented to prevent loss of soil during construction by stormwater run-off and wind erosion. The Plan will include protecting topsoil by stockpiling for reuse; preventing sedimentation of storm sewer or receiving streams; and preventing air pollution by dust and particulate matter. Temporary erosion and pollution control devices such as silt fences will be used to mitigate possible sources of pollutants.

Dewatering plans and associated measures will be implemented to control the inflow of groundwater into excavations. Measures may include use of earthworks such as perimeter ditches and sump pumps. Any discharge of water from the site will be conducted in accordance with applicable environmental guidelines.

All soils and surface water impacted via spills and releases will be disposed of off-site in accordance with all applicable environmental regulations and legislation.

Any liners will be tested for leakage during commissioning.


It is proposed that the outfall will be installed by a means to reduce impact to the environment. If possible, it will be installed in a dry environment, i.e. cofferdams, to isolate the sediment and erosion during outfall installation.

The proposed location of the WWTP will be fenced to minimize unauthorized access and wildlife conflicts.

4.3.4 Potential Causes of Resource Conflict Mitigation measures and best management procedures will be established and monitored to minimize all potential resource conflicts. Land Disturbance: Construction equipment will not be permitted to operate outside the construction zone to prevent damaging adjacent areas. Where possible, surface soil will be reused. Standard safety and environmental practices will be enforced to reduce and prevent potential conflicts caused by construction equipment and tasks. The project is located in a rural and undeveloped area; disturbance to surrounding properties is not anticipated. Surface Water and Surface Water Management: An Erosion and Sediment Control Plan will be implemented prior to construction and will describe the measures implemented to prevent loss of soil during construction by stormwater run-off or wind erosion, including protecting topsoil by stockpiling for reuse; prevent sedimentation of storm sewer or receiving streams; prevent pollution of the air with dust and particulate matter. Temporary erosion and pollution control devices such as silt fences will be used to mitigate the possible sources of pollutants. Following these requirements, minimal conflicts are expected. Groundwater: During excavation activities or removal of existing soil materials, there is a potential for interactions with groundwater. Dewatering plans and associated measures will be implemented to control the inflow of groundwater. Discharge of water from the site will be conducted in accordance with applicable environmental guidelines. All liners will be tested for leakage during commissioning. Following these requirements, no conflicts are expected. Fish and Fish Habitat: Construction activities will be designed and executed so as to minimize impacts to any body of water and, therefore, minimize effects on any fish or fish habitat areas. As such, all activities related to the outfall construction will be coordinated with the regulatory agencies at both Provincial and Federal levels. It is proposed that the outfall will be installed by a means that would reduce impact to the environment. If possible, the outfall will be installed in-the-dry with measures such as silt fencing and cofferdams installed to isolate the sediment and erosion during installation. Any culvert installations will follow best management practices and guidelines to reduce impacts to watercourses and fisheries. Following these requirements, minimal conflicts are expected. Wildlife: Short-term effects to wildlife are expected during the construction period. Operation of machinery, equipment, human presence, and noise may result in temporary avoidance behaviours by animals in the vicinity of the WWTP and associated Project components. Best management practices will be implemented for the handling of domestic refuse generated during construction in order to reduce potential for wildlife (i.e. bears) to opportunistically forage on these materials, hence becoming a nuisance. If problem wildlife/nuisance animals are encountered, the appropriate authorities will be contacted. Following these requirements, minimal conflicts are expected.


Vegetation and Forestry: The project area consists of forested areas. All equipment used on site will be clean and clear to prevent the spread of invasive weeds. Where practical, vegetation removal should be completed outside of the bird breeding period (typically April 1st to August 31st). If clearing is required within the bird breeding period, pre-clearing bird nest surveys will be required to be completed by a qualified biologist to ensure no active nests are destroyed or impacted by clearing. Following these requirements, no conflicts are expected.

Air Emissions and Quality: Air emissions and air quality measures will be implemented into the Environmental Management Plan to prevent pollution of the air with dust and particulate matter. All equipment and construction activities on site will occur during approved working hours and all equipment used on site will be in good working order to reduce effects of noise. Following these requirements, no conflicts are expected. Human Activities: The access road will be aligned from the existing roadway (Cooper Blvd.) to the WWTP site. This private road will be gated in order to restrict any unauthorized access to the WWTP area. If required, temporary traffic management will be implemented at the connection to Cooper Blvd. There are no registered homes or cabins in the vicinity of the proposed project. Though snowmobile and ATV trails in the area may intersect with the proposed access road, there is no expectation of any significant level of human conflicts.

4.4 Operations The WWTP will operate year round following construction, and will be sized to treat the future design flows shown in Table 4.4 for the year 2040. Flows were monitored at the existing treatment plants to establish current flows, and census data was used for 2016 populations. A program of sewer separation and rehabilitation is underway to reduce wet weather flows and bring average and peak flows per capita down to more typical ranges. Table 4.4 Proposed WWTP Flows

4.4.1 Environmental Impacts during Operation The Project will be operated so as to minimize risk and potential environmental impacts. Potential environmental impacts that have been identified include:

Controlled release of treated effluent (liquid or odour);

Uncontrolled release of treated effluent (liquid or odour);

Noise pollution from operation activities; and

Silt and sedimentation runoff.

4.4.2 Potential Source of Pollutants during Operations Potential sources of pollutants that may occur as a result of operation include the following:

Treated effluent;

Dewatered and biodegraded solids;

Parameter Units 2016 (Measured) 2040 (Design)

Connected Population capita 11,688 17,500

Average Day Flow (ADF) m³/day 8,994 10,500

Peak Day Flow (PDF) m³/day 20,346 23,800


Treatment chemicals;

Airborne exhaust emissions from operational equipment;

Odours;

Noise pollution from operational equipment; and

Storm water runoff from site.

4.4.3 Mitigation Measures during Operations The Town will follow all specified permit conditions and best management practices during operation. The following project specific mitigation measures will be implemented during operations to mitigate potential sources of pollutants from entering the environment:

All chemical systems shall be contained with separate drainage systems for each chemical dosing system.

Each chemical storage tank will be corrosion proof and shall have at least 110% the storage capacity of the largest tank.

Sumps will be located in the containment areas such that they can be pumped out with a small portable pump.

Unloading of tankers shall be carried out within a shallow containment or sloping area draining to an isolated sump (road tanker containment area). This sump shall be capable of being pumped out using the same pump as that provided to pump out the chemical tank containment areas. The drains adjacent to the sumps shall be connected to the sanitary sewerage system.

The treatment plant and related infrastructure shall be designed to minimize the production of odours. Specific engineered measures shall be in place to mitigate the propagation of odours, such as aeration, ventilation, and odour removal through bio-filters or chemical scrubbers. The proposed treatment plant location is in a rural area in order to avoid the risk of odour nuisance to neighbouring properties.

Noise from the WWTP when operating at full capacity with all systems operating normally, not including the emergency generator, shall not exceed 65 dBA at the plant boundary. Noise generation will be limited using the following design practices:

o Design equipment for normal operation at lower rotational speeds; o Locate noise generating equipment away from points of compliance; o Orient discharge stacks directly upwards; and o Use features such as sound traps, silencers, enclosures and sound walls.

Odour monitoring shall occur four times throughout the first year with a minimum of two months between samples. During each sampling event, six air samples, taken at two-hour intervals, will be taken at four sampling sites at the plant perimeter using a flux chamber. At least one sample shall be taken during worst-case odour dispersion scenarios (high temperatures, low wind speed) during a period of low flow. Samples shall be tested offsite using independent testing staff for odour units.

Provide adequate dust control and ventilation to any areas where dry powders are batched or stored.

Effluent quality will be monitored for compliance with applicable permits (Table 4.5).


Table 4.5 Compliance Sampling Requirements (WSER)

1 Effluent samples for compliance determination shall be based on the collection of a 24-hour composite sample every two weeks, separated by at least 7 days. Each composite sample shall include a minimum of 2 discrete samples, with samples evenly distributed throughout the 24-hour period. 2 Quarterly average compliance shall be based on composite sample results from each Quarter as defined in the WSER regulations. 4.4.4 Potential Causes of Resource Conflict Surface Water and Surface Water Management: The effluent from the proposed WWTP will meet or surpass the WSER and Provincial requirements. An effluent sampling program will be implemented to confirm that the effluent meets or exceeds the requirements for discharge into the environment. Following these requirements, no conflicts are expected. Groundwater: All liners will be tested for leakage during operations. Following these requirements, no conflicts are expected. Fish and Fish Habitat: The outfall will be both designed and scheduled for installation to reduce and minimize the impact on fish and fish habitat. All of the outfall work will be coordinated with the MAE and the Department of Fisheries and Oceans. The effluent to be discharged to Whitman’s Pond from the WWTP will be of better quality than the effluent from the current WWTP. Following these requirements, no conflicts are expected. Wildlife: There are no additional resource conflicts expected for wildlife during operation. Vegetation and Forestry: There are no additional resource conflicts expected for vegetation and forestry during operations. Air Emissions and Quality: Operations will be implemented so as to reduce effects from noise and odour. The WWTP is over 1,000 m from the nearest residential area; therefore, the undertaking is not expected to impact everyday human activity given the secluded location of the site. As such, no additional conflict is expected. Human Activities: The private road will be gated to restrict unauthorized access to the WWTP area. Though snowmobile and ATV trails in the area may intersect with the proposed Trunk sewer and access road, there is no expectation of any significant level of human conflicts.

1 INTRODUCTION

Englobe Corp (Englobe), at the request of MHPM Project Managers Inc., on behalf of the Town

of Gander, has carried out a geotechnical investigation at the locations of a proposed new

wastewater treatment plant (WWTP) and the associated new pipeline corridors. The purpose of

the work was to assess the subsurface and groundwater conditions in these areas.

This report presents the observations of the geotechnical investigation of the proposed locations.

Included herein are the factual results of the field investigation including discussion of field

procedures, subsurface conditions, and laboratory analysis.

It is understood that the Owner’s Technical Consultant (OTC) for the wastewater treatment

facility project is CBCL Limited (CBCL).

2 PROJECT DESCRIPTION

It is understood that the Town of Gander is planning for the replacement of their two existing

wastewater treatment plants, namely the Magee Road Sewage Treatment Plant and the

Beaverwood Sewage Treatment Plant, with a new wastewater treatment plant. The new facility

will be capable of treating all of Gander’s current needs as well as having the built-in capacity to

handle future growth of the municipality. The scope of work associated with this project includes

the construction of new trunk sewers, construction of a new wastewater treatment facility, and

decommissioning of one or both of the two existing sewage treatment plants or possible

refurbishment of the Beaverwood plant to serve as a combined sewage and storm water

treatment facility during high flow events.

The planned location of the new WWTP is northeast of Town of Gander and south of Whitman’s Pond. Site reconnaissance with the CBCL, found that the original proposed location of the

WWTP, just south of Whitman’s Pond, was a marsh. The proposed location was moved by

CBCL to along the northeastern boundary of the Bowater property. The new proposed location

generally slopes down gently to the northwest to Whitman’s Pond.

3 INVESTIGATION PROCEDURE

The fieldwork for the test pit investigation was carried out between November 27, 2015 and April

8, 2016. Sixty-two (62) test pits were excavated using an excavator supplied by ANW

Construction Limited. The locations of all test pits were provided by CBCL. Due to accessibility

issues, primarily boggy areas, some locations had to be altered. The approximate as-built test

pit locations are indicated on the enclosed site plans, Figure 1 and Figure 2. Test pit locations

were referenced in the field to UTM-NAD-83 Zone 22 Grid system using a held-held GPS unit.

The co-ordinates for each test pit location are shown in Table 1.

P20784


2

The site investigation was carried out by qualified geotechnical engineering personnel who

located the test pits in the field and logged the subsurface conditions. Grab samples were

obtained from the test pits and placed in waterproof bags and transported to our Mount Pearl

laboratory for further examination and testing.

The fieldwork for the monitoring well installation was carried out between June 21, 2016 and

June, 2016. Eight (8) boreholes were drilled using a truck-mounted drill rig supplied to the project

by Logan Geotech Inc. and were advanced through the overburden using standard solid stem

augers. Standard Penetration Testing and soil sampling were performed (where possible) in the

overburden using a 50-mm diameter split-spoon sampler. A 50 mm diameter PVC monitoring

well was installed in each borehole. Well details are shown on the Borehole Logs in Appendix

2. The approximate as-built test pit locations are indicated on the enclosed site plan, Figure 3.

Borehole locations were referenced in the field to UTM-NAD-83 Zone 22 Grid system using a

held-held GPS unit. The co-ordinates for each monitoring well location are shown in Table 3.

4 SUBSURFACE CONDITIONS

4.1 Soil Conditions

An explanation of terms and symbols used in the report is provided in Appendix 1. A summary

of the encountered geologic conditions is provided in the Test Pit Logs in Appendix 2. Laboratory

test results are provided in Appendix 3.

It should be noted that the stratigraphic boundaries on the Test Pit Logs typically represent a

transition of one soil type to another and do not necessarily indicate an exact plane of geologic

change. Subsurface conditions may vary between and beyond the test pit locations.

Groundwater observations were made during the field investigation through open-hole

measurement at the test pit locations. A summary of the accumulated groundwater information

is provided on the Test Pit Logs in Appendix 2 and in Table 1.

4.3 Groundwater Conditions

Each monitoring well was drilled adjacent to previous excavated test pit and the monitoring well

soil profile shown on the borehole logs is based on each corresponding test pit. The

approximate elevations shown in Table 3 are based on current available topographical

mapping of the site area. Note that for MW-B3 and MW-E3 elevation could not be determined

since available mapping did not cover these locations. For MW-C0 and MW-E0, the water

level in the wells had not stabilized when groundwater level was taken.

Based on observations during both field investigations, intermittent bog areas were

encountered in the proposed WWTP location. Therefore during excavation and removal of

existing peat/rootmat materials soils, control of inflow of groundwater into excavations will be

required. Where appropriate, the flow of water should be controlled by the earthworks

contractor by using perimeter ditches and sump pumps. Control of groundwater during site

preparation is a critical factor and dewatering plans should be reviewed by designers prior to

start of any construction activities. Discharge of water from the site must be conducted in

accordance with applicable environmental guidelines for sediment and any potential

environmental contamination concentrations.

5 CLOSURE

The geotechnical investigation undertaken has involved random sampling of site conditions.

Should any conditions be encountered during constructions that are contrary to those reported

herein, we request immediate notification so that reassessment can be undertaken.

Appendix 1 Explanation of Terms and

Symbols

SYMBOLS AND TERMS USED ON THE BOREHOLE AND TEST PIT RECORDS

SOIL DESCRIPTION

Behavioural properties (i.e. plasticity, permeability) take precedence over particle gradation in describing soils.

Terminology describing soil structure:

Desiccated - having visible signs of weathering by oxidationof clay minerals, shrinkage cracks etc.

Fissured - having cracks, and hence a blocky structureVarved -composed of regular alternating layers of silt

and clayStratified - composed of alternating layers or different soil

types, e.g. silt and sand or silt and clayWell Graded - having wide range in grain sizes and substantial

amounts of all intermediate particle sizesUniformly Graded - predominantly of one grain size.

Terminology used for describing soil strata based upon the proportion of individual particle size present:

Trace, or occasional Less than 10%Some 10-20%Adjective (e.g. silty or sandy) 20-35%And (e.g. silt and sand) 35-50%

The standard terminology to describe cohesionless soils includes the relative density, as determined bylaboratory test or by the Standard Penetration Test ‘N’ - value: the number of blows of 140 pound (64 kg)hammer falling 30 inches (760 mm), required to drive a 2 inch (50.8 mm) O.D. split spoon sampler one foot(305 mm) into the soil.

Relative Density ‘N’ Value Relative Density %

Very loose <4 <15Loose 4-10 15-35Compact 10-30 35-65Dense 30-50 65-85Very Dense >50 >85

The standard terminology to describe cohesive soils includes the consistency, which is based on undrained shearstrength as measured by insitu vane tests, penetrometer tests, unconfined compression test, or occasionally bystandard penetration tests.

Consistency Undrained Shear Strength ‘N’ ValueKips/sq.ft. kPa

Very Soft <0.25 <12.5 <2Soft 0.25-0.5 12.5-25 2-4Firm 0.5-1.0 25-50 4-8Stiff 1.0-2.0 50-100 8-15Very Stiff 2.0-4.0 100-200 15-30Hard >4.0 >200 >30

SOIL SAMPLES

CONDITION – This column graphically indicates the depth and condition of the sample:

TYPE – The type of sample is indicated in this column as follows:

A auger sampleB block sampleC rock core, or frozen soil coreD drive sampleG grab sampleSS split spoonP Pitcher tube sampleU tube sample (usually thin-walled)W wash or air return sampleO other (see report text)

PENETRATION RESISTANCE – Unless otherwise noted this column refers to the number ofblows (N) of a 140 pound (63.5 kg) hammer freely dropping 30 inches (0.76 m) required to drive a2 inch (50.8 mm) O.D. open-end sampler 0.5 feet (0.15 m) to 1.5 feet (0.45 m) into the soil, oruntil 100 blows have been applied, in which case, the penetration is stated.

GARBAGE REGULATIONS & SCHEDULES

Updated: August 2016

The Town of Gander reminds residents that Garbage and Refuse Regulations require that household garbage

be placed at the concrete curb no earlier than 6 a.m. and no later than 8 a.m. on your scheduled collection

day. Household waste must be separated into two streams, with all recyclables placed in transparent blue

bags and non-recyclable waste in transparent clear bags.

Note: All garbage placed for collection shall be covered by metal or plastic container, netting or

blanket from April 1st to November 30th every year.

A limit of six (6) bags per household will be accepted on each scheduled collection day. Empty containers and

any garbage/refuse not collected under these regulations must be removed from the curb before 8:30 p.m. the

same day.

Please heed the following guidelines for safe disposal of hazardous items:

• Needles must be in a container such as steel or heavy plastic that will prevent accidental puncture to those

collecting it.

• Broken glass should be placed in a separate container and marked as such.

• Hot coals/ashes must not be put out for collection.

Complete Garbage and Refuse Regulations, along with the regular collection schedule, may be found by

clicking here, or by calling the Public Works Depot at 709-651-5938.

7:02 – Introduction of Project (Greg Sheppard)

CBCL started with the project in 2014.

Project delivery methodology is Design‐Build.

Preliminary engineering was completed in early 2015.

Eight design‐build teams responded to a Request for Quotations (similar to an

Expression of Interest) which was issued in 2015. Four teams were short‐listed and will

be invited to respond to a Request for Proposals. Teams will be evaluated using various

criteria; parameters may include: technology, price, and schedule.

7:05 – Introduction to the Environmental Assessment Process (Melissa Rutherford)

Project is required to be registered as an undertaking under Environmental Protection

Act and the Environmental Assessment Regulations.

The Registration Document will be submitted to Newfoundland and Labrador

Department of Municipal Affairs and Environment (MAE).

The Minister will have 45 days to review and provide comment on the Registration

Document. MAE will post notice of their decision within 10 days of the 45 after

registration.

After submission, MAE will have 7 days to publish the notice and the public will have 35

days to provide comment after the notice is published.

The Registration Document will include the information as required by the

Environmental Assessment Regulations and includes information such as the description

of the project, environmental background, employment , schedule, and funding.

summarized responses are presented in Table 1.

8:10 – Meeting closed by Council Table 1 Question Themes and Responses

Theme Topic Response

Environmental Assessment Process

Environmental Assessment Timeline How will the Registration Document be submitted in absence of the final process technology?

The Minister has 45 days to review the registration document and 10 days to post the decision after the 45 days. CBCL has been in discussions with MAE regarding this issue; the Registration Document will be submitted outlining the potential technology processes at a high level.

Project Process Detail How does the Environmental Assessment impact the overall project schedule? How was the location selected? What buffer will be around the proposed WWTP? How far is the project from the development areas? Has the location been selected based on allowing adequate space for future development?

The WWTP will use either land‐based or mechanical processes. The technology will be decided on during the design‐build contractor selection process. Construction activities will not be able to occur until after the undertaking is released from the Environmental Assessment process and other permits have been obtained. Site selection was based on the need to be outside of the Gander Lake watershed, the need to be close to existing treatment plants, and the need to reserve adequate space for future land development. The buffer is 100 metres. The proposed site is located ~ 2 km East of Cooper Blvd. Yes, this was considered in consultation with the town.


Theme Topic Response

How will the location of the trunk sewer be selected?

The trunk sewer alignment will be selected as to minimize effects to potential development areas and current rights‐of‐way.

Environmental Concerns

Have studies been complete to determine how the project will affect Jonathon’s Pond? Will snowmobile trails be impacted; one trail might intersect the trunk sewer and road alignment? There may be an unregistered winter cabin on Whitman’s pond.

Specific studies have not been completed on Jonathon’s Pond. The effluent to be discharged to Whitman’s pond will be improved over the current discharged effluent from the Magee Road WWTP. Access along the access road may be restricted. Snowmobile crossings can be marked along the road alignment. Impacts are not expected. The comment was noted by CBCL; no impacts expected for cabin use if present.
